When detectives launched an investigation on Mata, they discovered he received partially nude photos of two Santa Catalina students in exchange for buying them alcohol.

"Mata was involved in multiple criminal acts with at least two minors at the school between November 2012 and January 2013," Sonne said.

The two girls were boarding students and have since been expelled from Santa Catalina School. The school is one of the most prestigious private Catholic schools on the Central Coast. It's co-ed from preschool-8th grade, and all-girls from ninth-12th grade.

Mata was arrested by Monterey police officers on Jan 17.

He was booked into the Monterey County Jail on 10 felony charges, including contributing to the delinquency of a minor, sending harmful material to a minor, and committing lewd and lascivious acts against minors.

Mata's bail was set at $250,000 and he pleaded not guilty at his arraignment Tuesday afternoon.

Mata is an illegal immigrant who had been previously deported from the U.S. School officials and police investigators said no other students have been identified as possible victims.
